I have been testing roms for quite some time now but i've come across a strange issue. I got a bootloop and tried flashing the stock rom but windows gives error that device has malfunctioned and windows is not able to recognise it. Although the cwm recovery is working well it can't mount emmc so i'm not able to flash another rom. I'm pretty struck in the middle. I tried flashing via usb otg but cwm isnt detecting otg too. It would be of great help if someone would help me out of this. Is the device completely dead ? Will i be able to recover it ? any help would be really appreciable

Hi,
I don't know what device you have. Reboot your PC, delete your drivers and install the adb drivers again. Also try different usb ports/cables.

I just rooted my A510 and ever since my laptop won't recognize my tablet. What can I do? I've tried factory reset, as well as flashing cm10/other roms. I downloaded the os from the acer website but don't know how to flash. Can anyone help me out?
Recovery= cwm
rom = cm10 unofficial
Update I was able to flash back to stock with unlocked bootloader and recovery from the acer website. But still I cannot get any computer to recognize my tablet. I have also lost root. What can I do now? Charging works perfectly so micro usb slot is not messed up.
Did you try another USB Cable ? another PC ?
What's no working ? MTP ? USB Mass Storage ? ADB ? Fastboot ?
Yes I've tried different USB and computers. The problem is that the computer won't recognize tablet in any mode. I'm currently on stock recovery with stock ww jb. I have us version of the tablet. Also update. zip not working in stock recovery. Idk if this is related but this problem occurred after unlocking boot loader also cwm would not mount ext SD. Boot loader is still unlocked. Maybe locking again will fix?
Edit: When in fastboot mode I am able to get usb device not recognized error in windows but have not been able to get it to recognize the device. I have tried pointing driver to acer official drivers but windows rejects these drivers. Device shows up as unrecognized device under device manager in windows and tablet fastboot mode.
Edit2: Windows gives same usb device not recognized error as in fastboot when plugging in using debug mode. Still no solution to this problem.
anybody know how I can fix this? Maybe flashing bootloader again can fix problem? Someone please help!

yes, you might try to flash all the Firmware using Acer ADT and a full Firmware file (BIN)

This sounds more like a Windows issue. What version of Windows? The Acer drivers only support Win XP or 7. If you load the Android SDK, those drivers can be made to work. If the USB on the tab recognizes a flash drive, I say look at Windows to resolve.
Also, I believe that once the bootloader is unlocked, it cannot be locked. It maybe can be replaced with a locked one using the fastboot flash command.
Acer Drivers are compatible with Windows 8 x64 (I'm using it)

How would I do that? ADB doesn't recognize the device neither does fastboot. Idk if it is a windows problem since I have tried updating drivers over and over again. I get an error returned saying usb device not recognized. Also I'm having trouble flashing in stock recovery. I put update.zip on root of sd card and external sd but nothing works. External sd doesn't show in recovery.
I'm now having trouble getting the pc to recognize the tablet at all.
Someone Please help.

I would suggest making a Linux thumb drive (http://www.ubuntu.com/download/desktop/create-a-usb-stick-on-windows). You don't have to futz with drivers as much in Linux. All ADB and Fastboot commands are available. I used it for my phone and my TF101. An old 2GB USB will suffice.
Any utilities, files, etc. can be placed on the stick for use, as well.
so basically I should boot my computer using a usb drive then connect my tablet to another usb port correct? Also I'm starting to think my usb drivers in the tablet itself are messed up from trying to root. How would I fix that? But I will try what you said first. Thanks
Btw I am unrooted now cuz I flashed Acers stock firmware but it didn't lock bootloader which is weird.
I have tried using the usb stick to boot into linux but that would not recognize my tablet as well. My phone was recognized immediately but my tablet was not. The tablet won't even recognize that a usb is connected when it is connected to the computer, but shows charging when connected to charger. Again I think the usb drivers in the tablet itself are messed up. What can I do?
Do you guys think I could possibly do something in APX mode? Seems like it may be my only hope
anybody?

If you still have the USB adapter, try connecting a USB stick to the tablet. If the tablet mounts the stick and you can view files, then there is most likely nothing wrong with the tablet USB. If not, then Acer may still be able to help with a warranty claim. I bought the extended warranty w/ mine.
As I stated earlier, once the bootloader is unlocked, it can't be locked... perhaps replaced, but not locked.
If the USB functions, boot to the Linux stick and run ADB usb.
then plug in the device to see what happens...
Pretty much all you can do in APX is flash the factory image. that's the most primitive state for android devices...
http://forum.xda-developers.com/wiki/APX_mode
You would still need a functioning USB port.
Hope this helps.

I tried plugging in the usb drive with the adapter and the tablet was unable to recognize the usb. does this mean that the usb drivers are bad? What are my options? What happens if Acer denies me support due to being out of warranty?

Sounds like a hardware or physical problem. Inspect the contacts on the USB for an obstruction or a misaligned contact. There are 5 contacts on my A700. I would power down before messing with it. Also, check for a loose socket... you did say that the charger works, though.

Yea the charger works perfectly fine so I don't think that is the problem. It may be usb drivers in the bootloader or something cuz this problem started right after I unlocked the bootloader.
I contacted Acer and they said my tablet is out of warranty and to fix it it'll cause $250. Is there anything else I could try?

I really don't believe the USB driver was changed when you unlocked the boot-loader. If you replaced the Kernel, that would more likely. This is resolvable by replacing the kernel with stock...doable if you can flash from recovery.
Again, I say inspect the USB contacts. they are really tiny and delicate. If one is crossing another, this can cause your issues. They can be straightened with a lot of patience.
It would be very hard to find the USB port for sale as it is unique to Acer... with the 12VDC capability.
Thanks I will carefully look at the pretty itself. I did not change the kernel before the problem started occurring but did flash cm10'1 to see if that would fix problem amd it didn't. Thank you very much for all of your help!

the micro usb ports pins seem straight to me, they are perfectly aligned. I'm seriously at a loss as to why it still won't work.
I have a TF101 SN60 - SBK1. I was trying today to root it to instal a stupid USB modem app and i bricked it.
Right now it is in recovery mode and i can`t get it out. Tried all the combination of the buttons and still doesn`t work.
I tried to reput the stock rom from Asus and i had success(2 times) but was still in recovery mode and after that i tried once more and it failled.. now i have 7 " !!!!! phone update failled !!!!" and i am very pissed and mad as i do not know what to do no more. I wasted 5 hours today trying to do something to it but i can`t no more. Please help me with some tips or maybe help me put it back to it`s normal state. Thank you.

Have you tried APX mode?
I would try another PC, or get a new charging cable. It is possible for the USB cable to charge but not work for USB. Happened to me.
Hi guys hopefully I posted this in the right place. I have a rooted Nexus 5 with multirom installed and had a few ROMs in mind that I wanted to try out, most of them just installed simply and booted without problems however when I chose to try and install slimrom or another (can't remember the name of the other ROM sorry) a message would appear stating I need to install a different bootloader IMG to install/ boot that ROM. I searched around for a while and found an image to install through twrp but when I installed it I now can't boot the phone to launch a ROM or get into recovery mode as the screen will go black. Any ideas? I'm trying to used adb to install a twrp img but so far it doesn't detect the device :/ I would much appreciate any help or suggestions! Ask me if you have any questions! Thanks.
Have tried to flashing back to a completely stock rom?
Problem is I can't get my computer to recognize my nexus 5 in the boot loader mode if I could I could then flash twrp again and flash the stock rom but it doesn't detect
Does the phone boot into fastboot mode? You tried different USB ports, cables, computers, and operating systems?
The only mode I can get my Nexus into is boot loader mode so yes fast boot. I have a windows xp and 8 so I use 8 as its the only PC that I can run adb & fast boot on without problems. I have used a USB cord the recognized my sisters phone also so it shouldn't be a faulty cable I'm pretty sure. Thanks for those ideas I appreciate your help a lot!

Use the cable that came with the phone.
Use this well made thread
http://forum.xda-developers.com/google-nexus-5/general/tutorial-how-to-flash-factory-image-t2513701
I once wiped my system and rebooted and got stuck in a loop. at his thread is what I used to save my phone. Hope it helps.

Speaking from personal experience, I found that the USB cable could make a difference. I also have Samsung phones and, although the USB cable allowed win7 to install drivers, I could never flash anything. Once I switched back to the original cable, flashing works without any problems.
tahnks guys i managed to fix my problem using the nexus in bootloader mode on Windows 7 as windows 8 and xp wouldn't recognize it for some reason. From there i managed to install twrp reset the device, flash theserurection remix rom and flash a correct bootloader. Thanks for your help as it lead me in the right direction!
Hi there.
I have an U11 now and I am quite happy with it.
But there is one problem.
It takes ages till I see the U11 appearing on the PC. USB debugging is on, data transfer chose at the U11, tried several USB connections on the PC tried even another laptop.
Sometimes it is even not showing the phone.
Are here people around who are facing the same problem?
Any solutions?
Thx a lot.
Schuertzi
Yeap exactly the same...
No problem here, each new usb port you connect to loads the drivers and takes a few seconds but after that connection is fast.
Thing that has me peeved is the lack of OTG support. I like to backup straight to an external HDD. No go with the U11.
Tried and waited really long after the drivers were installed. Nothing changed really. Even with using the same USB connection.
May be I did something wrong during flashing TWRP and then the Viper ROM.
Will check and let you know.
Thx

I had the same issue even though i didnt root. I tried on multiple pcs and still got a message saying usb device not recognized. So i returned it and ordered the solar red. I should receive it today and I'll let you know if I still get the same result.
Great, just let us know.
Thx
Hi Guys,
I solved my problem.
I had first the wrong TWRP installed then deleted. Tried then again to install via fastboot. Was not possible.
Then, I installed the official TWRP app from the playstore. Installed the actual TWRP from there. And voila, TWRP installed, rebooted and everything works.
Just for your info. May be you have similar problem.
Schuertzi.
So i definitely had a defective device as this new one connects without any issue.

I can use external HDD and pendrives. In fact, the u11 recognises NTFS even.
Hey Guys,
in the last weeks a problem with my USB-Port occured. About 2 weaks ago i was able to plug in an usb drive and backup my system onto it via twrp. Yesterday i wanted to refresh the backup and twrp did not recognized the drive. I restarted the phone, and flashed the newest version of twrp via odin. Still not recognizing any usb storage. Then i booted up and pluged the usb storge in ... still not detected.
Even when i connect the phone to my pc it is not detected. The only way to connect my phone to the pc, ist by using the download mode and flash something via odin.
Now I'm confused. Is the USB-port not working or is something wrong with the software. Should i flash a 4 Port firmware and install everything again?
And why the **** is the phone detected while its in downloadmode but not detected in any other mode (recovery, booted up, shutdown etc.) ?
I appreciate any advice
Flash Stock Rom
I tried to flash the stock rom and it didn't solve the problem.
Its so strange i can flash roms and recoverys using the download mode. But in any other mode the usb storage is not detected. Even beeing in the twrp i cannot get the an usb-stick to be detected. Actually im pretty sure the usb-port is broken, but as i said i appreciate every advice.
Last idea i have is to flash a 4 part firmware, but i not sure wheather this would change anything.

If different ROMs don't fix it then yes your USB is FUBAR. The functionality of low end operations such as download mode work because they use very little. Does it charge?/
